First-Party Coverage
First-party coverage is insurance that pays the policyholder for its own covered losses, such as damage to its property, lost income, or cyber incident response costs. It differs from third-party coverage, which responds to claims other people make against the insured.

How first-party coverage works
IRMI describes first-party insurance as insurance that applies to the insured's own property or person. The claim runs between the policyholder and its insurer, and payment goes to the policyholder, subject to the policy's limits, deductibles, waiting periods, and valuation terms. Because no outside claimant is involved, there is generally no duty to defend. The insured instead documents the loss and proves it.
Common first-party coverages include property insurance, business interruption, and crime coverage for the insured's own stolen funds. Cyber policies often contain a first-party section for breach response, data restoration, extortion, and lost income. Third-party coverage is the counterpart: liability policies such as general liability, professional liability, and D&O respond when someone else claims the insured caused them harm.
Common types of first-party coverage
- Property. Pays for damage to buildings, equipment and contents. See property insurance.
- Business interruption. Replaces lost income and covers continuing expenses while operations are disrupted. See business interruption.
- Contingent business interruption. Addresses income lost because a supplier or other dependency was disrupted. See contingent business interruption.
- Crime. Covers the insured's own funds or property taken through theft, fraud or employee dishonesty. See crime insurance and social engineering fraud.
- Cyber first-party. Covers breach response, data restoration, extortion and lost income after a cyber event. See ransomware coverage.
- Key person. Pays the company if a critical person dies or cannot work, depending on the policy. See key person insurance.
Example
A hypothetical fintech company suffers a ransomware attack that locks its systems for five days. The first-party section of its cyber policy may pay for forensic investigation, system restoration, and lost income after the waiting period, subject to its terms. Customer lawsuits over the same incident would be handled under the liability section, which is third-party coverage.
What to watch for
- Sublimits and waiting periods can sharply reduce what a first-party claim pays.
- Valuation matters. Property may be paid at actual cash value or replacement cost.
- Proof of loss and documentation requirements are usually strict, and deadlines apply.
- Many policies bundle both types of coverage. Check which section applies to which part of a loss.
- Exclusions and covered-peril lists decide whether a loss qualifies, so a loss can be real but not covered.
- Deductibles and retentions apply before payment starts, and business income coverage often begins only after a waiting period has passed.
- Keep records of costs and downtime as they happen. Insurers commonly ask for invoices, logs, and other evidence, and a clear paper trail supports the claim.
First-party vs. third-party coverage in practice
- Who is paid. First-party payment goes to the policyholder. Third-party payment goes toward claims by others, or to those claimants through settlement or judgment.
- What triggers coverage. A first-party policy responds to a covered loss. A third-party policy responds to a covered claim, such as a demand or lawsuit.
- Defense. First-party claims generally do not involve a duty to defend. Liability policies often do. See duty to defend.
- Proof. In a first-party claim the insured documents and proves the loss. In a third-party claim the insurer largely responds to the claimant's allegations.
- Recovery. After paying a first-party claim, an insurer may pursue the party that caused the loss. See subrogation.
A second example: a lab fire
A hypothetical hardware startup has a fire in its test lab that destroys equipment and halts production for several weeks. Its property policy may pay to repair or replace the equipment, depending on whether it is valued at actual cash value or replacement cost. Its business interruption coverage may replace lost net income and cover continuing expenses after a waiting period, up to the stated limit and for the period of restoration the policy allows. The company's records of damaged items, downtime and extra costs support the claim. If a customer later sues over late deliveries, that would be a third-party matter under a liability policy, not the property policy.
Questions to ask your broker or underwriter
- How are losses valued, and does the policy include a coinsurance requirement?
- What are the waiting period and the maximum period of restoration for income loss?
- Which causes of loss are covered or excluded, and which are sublimited?
- Does the policy cover loss caused by a vendor or cloud provider outage?
- For digital assets, are there conditions on how assets are stored or secured?
- What proof of loss is required, and by when?
What documents to keep for a first-party claim
- Inventory and valuation of damaged or stolen property.
- Invoices, receipts and logs for emergency response and repair costs.
- Financial records that show income before and during the disruption.
- Incident timelines, photos, system logs and reports to authorities where relevant.
- Communications with the insurer, including when and how notice was given. See first notice of loss.
Why it matters for technology, AI, fintech and digital-asset companies
Most losses for these companies are non-physical: ransomware, funds transfer fraud, and system downtime. They fall under cyber or crime first-party coverage rather than traditional property forms. For digital assets, whether a first-party policy responds depends heavily on the wording. See digital assets and crypto.
Hardware, robotics and data center operators have physical assets that a property form addresses, and their dependence on power, cooling and suppliers makes business interruption terms important. Software, AI and digital-asset companies rely on systems and keys instead, so the first-party questions are about downtime, restoration and theft. Because these companies depend on third-party vendors, check whether dependent or contingent coverage exists. For more, see property insurance and physical AI and hardware.

Frequently asked questions
What is first-party coverage?
First-party coverage is insurance that pays the policyholder for its own covered losses, such as damage to its property, lost income, or cyber incident response costs. It differs from third-party coverage, which responds to claims other people make against the insured.
What is the difference between first-party and third-party coverage?
First-party coverage pays the insured for its own losses. Third-party coverage, or liability insurance, responds when someone else claims the insured caused them harm and typically pays defense costs and damages owed to that claimant. Some policies, like cyber, include both.
Is cyber insurance first-party or third-party?
Cyber policies usually include both. The first-party section can cover the insured's own breach response, data restoration, extortion, and lost income. The third-party section covers liability claims from customers or others. The exact split depends on the policy.
Does first-party coverage include a duty to defend?
Generally no. A duty to defend applies to liability claims made by others. With first-party coverage, the insured files a claim with its own insurer, documents the loss, and the insurer decides coverage under the policy terms.
Is business interruption insurance first-party coverage?
Yes. Business interruption pays the policyholder for its own lost income and continuing expenses after a covered loss, so it is first-party coverage. It is often bought with property insurance and subject to a waiting period and a period of restoration.
Does first-party coverage pay for my customers' losses?
No. First-party coverage pays you for your own losses. A customer's claim against you is a third-party matter, which would be addressed by a liability policy, such as professional liability or general liability.
What is a waiting period in first-party coverage?
A waiting period is the time after a loss begins during which income-loss coverage does not yet pay, often measured in hours or days. The policy sets its length, and it applies in addition to any deductible or retention. Cyber and business interruption forms often use one.
What documents do I need for a first-party claim?
Typically proof of ownership and value, invoices and receipts, financial records, photos or logs, and a written account of what happened. The policy may require a signed proof of loss within a deadline, so check its conditions.
